As a System Integration Test Engineer, you will integrate and verify Shield AI's Hivemind mission autonomy software directly on Autonomous Collaborative Platform (ACP) flight hardware. You will serve as the hands-on technical bridge between autonomy algorithms and physical aircraft systems, working across Shield AI and aircraft platform vendors to verify system interfaces, validate edge compute performance, and resolve integration issues before flight testing.

You will drive integration across Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments, both in Shield AI's internal laboratories and on-site at platform vendor integration facilities (including SIL, HIL, and iron bird test benches). You will turn high-level program objectives into executable integration plans, schedules, and test cards, systematically uncovering interface gaps early and formulating technical solutions to close them. This is an essential, high-impact role for an engineer who excels at the intersection where complex mission software meets real aircraft avionics and hardware.

• Integrate Mission Autonomy on ACP Hardware: Deploy, integrate, and verify Hivemind mission autonomy software with actual ACP software and hardware in ShieldAI and platform vendor SIL and HIL labs.
• Develop Test & Integration Plans: Develop detailed integration test plans, test cards, schedules, and objective success criteria across lab, ground, and flight test phases.
• Identify & Resolve Integration Gaps: Proactively identify architectural, interface, protocol, timing, and hardware/software gaps early; formulate concrete gap-closure plans, risk mitigations, and technical workarounds alongside Shield engineering and platform partners.
• Coordinate Joint Vendor Lab Execution: Partner directly with aircraft OEMs and platform vendors to coordinate lab readiness, align entry/exit criteria, deconflict bench time, and co-execute joint integration campaigns.
• Conduct Hands-On Lab Triage: Execute integration tests, configure test benches, and lead real-time troubleshooting of multi-system anomalies
• Drive Test Automation & Tooling: Coordinate across engineering teams to design and build test automation and simulation scripts to accelerate development
• Gate Flight Readiness & Support Flight Test: Enforce empirical test entry/exit criteria to gate delivery to aircraft ground and flight test; support flight test preparation, configuration validation, real-time troubleshooting, and post-flight data analysis.
• Support travel to test sites, customer events, and integration activities as required

• Typically requires 5+ years of relevant experience with a Bachelor's degree in Aerospace, Electrical, Computer, Mechanical, Systems Engineering, or related technical field, or 3+ years with a Master's degree.
• Lab & Hardware Integration:
  Demonstrated experience in system integration and test, including SIL, HIL, simulation, and flight test environments.
• Test Planning & Documentation:
  Proven ability to author clear, comprehensive integration test plans, procedures, and test cards, and translate test results into actionable engineering findings and gap closure roadmaps.
• Troubleshooting & Analysis:
